Ubuntu Mini 20.04 doesn't give any sound

I have tried to get sound working on my ubuntu mini installation but it seems to be stuck at 0% or muted.

I have a base system installation with Xorg and Openbox. On top of that, Firefox (to see if the sound works).

I have tried to set it with pactl set-sink-volume @DEFAULT_SINK@ 100% but it seems to have no change.

P.S. Installed from Ubuntu Mini 18.04 ISO and upgraded to 20.04

This is what aumix looks like

This is what sudo alsamixer does

Doing the amixer command results in amixer: Mixer attach default error: No such file or directory doing that with sudo, gives me some mixer output thing

How could I fix this?

edit:

Doing alsactl init and lspci -v | grep -A7 -i "audio" shows these outputs

sudo aplay -l shows this output

pacmd then list-sinks shows this

Executing aplay /usr/share/sounds/alsa/Front_Center.wav doesn't play anything but gives no errors, running it with sudo does however play the sound. This leads me to believe it's just a permissions issue

Since you apparently began from a Netboot (mini.iso) install, what leads you to believe that a complete audio stack is now installed? Or are you asking how to install it?

@user535733 is there a way to check if it's installed, and if not, how can I install it?

Does this answer your question? [Which packages should be installed to have sound output working on minimal Ubuntu 20.04 LTS?](https://askubuntu.com/questions/1349221/which-packages-should-be-installed-to-have-sound-output-working-on-minimal-ubunt) ← check this Q&A, in my case `sudo apt install pulseaudio alsa-base alsa-utils vlc --no-install-recommends ; sudo usermod -a -G audio $USER` was enough. Installation from mini.iso is very flexible.

@N0rbert thank you, I have come to that conclusion as you were writing the answer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
